This does a new import of the vendor, so it's not answering my concern. The
problem I'm thinking of is the following:
1) svk import of libcomplex 1.1
2) svk cp: use 1.1 in my project
3) svk import of libcomplex 1.2
4) svk smerge: upgrade to 1.2 in my project
Now, how can I get back to version 1.1?

There is a merge management facility: it's called svnmerge.py. My point is
that I simply don't need it because it's enough to issue a single "svn
merge" command with the correct URL. In the above case, I need something
svk merge //project/vendor/libcomplex/1.2 //project/vendor/libcomplex/1.1 .
[this assumes you have already find out that you're using libcomplex 1.2.
Notice that there is no way to find out which version you are using, without
a manual inspection of the log]. After this command, I believe you cannot
use svk smerge anymore.
Now compare this with what I plan to do:
$ cd ./project-wc
$ svnimport.py ls
$ svnimport.py ls -l
libcomplex: 1.1, 1.1b, 1.2
libbar: 2.4.8, 2.4.9, 2.4.12
$ svnimport.py copy libcomplex
Copying libcomplex into the current project (version: 1.2)
$ svn ci -m "Imported libcomplex 1.2"
$ svnimport.py info libcomplex
Available versions: 1.1, 1.1b, 1.2
$ svnimport upgrade libcomplex --version=1.1
Downgrading libcomplex to 1.2
$ svn ci -m "Downgraded libcomplex"
Available versions: 1.1, 1.1b, 1.2
See how there are absolutely no URLs, and all the information are being
provided in a way to totally hide the remote URLs. This is what I call a
user-friendly interface. When I think of a graphical tool for handling this
(like a boosted version of TortoiseSVN with svnvendor.py integrated), I
think I should see the copied libcomplex within the project with a different
color, telling me it's a vendor import; I would be able to right-click on
it, and select "upgrade"; this would pull up a menu with the list of
available versions, let me pick one and press OK; and that's it! no URLs
So this script is not a mere "powerful convenient import ala svk import"
(even though this is one of the biggest concerns). And it's not about
"merge-tracking for vendor branches ala svk smerge" (I do that everyday with
svnmerge.py, and it works well for me). It's a fully hi-level, opaque layer
for vendor branch management.
Did you read it the design document through?
